Ultrasound-Assisted Preparation of Chitosan Oligosaccharide-Stabilized Thyme Oil-in-Water Nanoemulsions: Enhanced Storage Stability and Antimicrobial Properties

mycolabadmin

Researchers created tiny droplets of thyme oil mixed in water using sound waves and a natural stabilizer from shellfish shells. These droplets stayed stable for weeks without separating and worked twice as well at fighting bacteria and mold compared to regular thyme oil. The new formula could be used to keep fresh food from spoiling during storage.

Glucose-6-Phosphate Dehydrogenase Modulates Shiraia Hypocrellin A Biosynthesis Through ROS/NO Signaling in Response to Bamboo Polysaccharide Elicitation

mycolabadmin

Researchers discovered that a naturally derived compound from bamboo boosts the production of hypocrellin A, a promising cancer-fighting and antimicrobial agent made by a special fungus. By studying a key enzyme called G6PDH, they found that it acts as a molecular switch controlling hypocrellin production when the fungus senses bamboo components. This discovery enables cost-effective large-scale production of this powerful medicine through simple fermentation, potentially making novel cancer treatments and antibiotics more accessible.

Effect of Antibacterial Peptide Microsphere Coating on the Microbial and Physicochemical Characteristics of Tricholoma matsutake during Cold Storage

mycolabadmin

This research demonstrates that coating expensive wild matsutake mushrooms with special antimicrobial peptides wrapped in tiny polymer microspheres can keep them fresh for up to 20 days instead of just 1-3 days. The coating works by protecting mushrooms from water loss, microbial spoilage, and browning while preserving their texture and nutritional quality. This edible coating technology could help mushroom producers sell their products over longer distances and extend availability of these prized wild mushrooms.

Ganoderma lucidum inspired silver nanoparticles and its biomedical applications with special reference to drug resistant Escherichia coli isolates from CAUTI

mycolabadmin

Researchers created tiny silver particles using a medicinal mushroom called Ganoderma lucidum to fight dangerous bacteria that resist antibiotics and are associated with urinary catheter infections. These nanoparticles were found to effectively kill drug-resistant bacteria, work as antioxidants better than a common antioxidant standard, and showed promise in killing breast cancer cells. This eco-friendly approach offers a natural alternative to conventional antibiotics for treating serious antibiotic-resistant infections.

Microbial-Based Green Synthesis of Silver Nanoparticles: A Comparative Review of Bacteria- and Fungi-Mediated Approaches

mycolabadmin

Scientists have developed environmentally friendly ways to create tiny silver particles using bacteria and fungi instead of harsh chemicals. These silver nanoparticles can fight bacteria, help treat cancer, clean contaminated water, and improve food packaging. The review shows that bacteria produce particles quickly but fungi are better for large-scale production and create more stable particles.

Evaluation of Salvia yangii Extract as a Promising Protective Raw Material Applied Topically to the Skin

mycolabadmin

Russian Sage (Salvia yangii) extract shows promise as a natural ingredient for skincare products. The study found that the plant contains compounds like rosmarinic acid that provide antioxidant, antimicrobial, and anti-aging benefits. When used at appropriate concentrations, the extract protected skin cells from sun damage and helped inhibit enzymes that break down skin collagen. This research supports the use of S. yangii in developing safer, more effective natural cosmetic products.

Deoxynucleosides as promising antimicrobial agents against foodborne pathogens and their applications in food and contact material surfaces

mycolabadmin

Researchers found that two nucleoside compounds (ddA and FdCyd) can effectively kill harmful bacteria like Vibrio and Salmonella that form slimy biofilms on seafood and food preparation surfaces. These compounds work by damaging bacterial cell membranes and preventing bacteria from communicating with each other. When combined with a food additive already used in the meat industry, these nucleosides become even more effective at much lower doses, potentially making food safer while reducing residual chemical effects.

Chemical Composition and Biological Activities of Psilocybe Mushrooms: Gaps and Perspectives

mycolabadmin

This review examined research on Psilocybe mushrooms and their chemical compounds, particularly psilocybin and psilocin, which show promise for treating depression and anxiety. The authors found that while these psychoactive compounds have been extensively studied, many other chemical substances in these mushrooms remain unexplored. Additionally, preliminary studies suggest these mushrooms may have antimicrobial and antioxidant properties, though more research is needed. The review highlights significant gaps in understanding the full potential of Psilocybe mushrooms for medical applications.

Extracellular Biosynthesis, Characterization and Antimicrobial Activity of Silver Nanoparticles Synthesized by Filamentous Fungi

mycolabadmin

Researchers used three types of fungi to naturally create tiny silver particles that can kill harmful bacteria and fungi. These particles were much smaller than the width of a human hair and proved especially effective against dangerous bacteria like those causing hospital infections and Candida yeast infections. This green manufacturing method is safer for the environment than traditional chemical approaches and could help address the growing problem of drug-resistant infections.

A New Species and Five New Records of Talaromyces (Eurotiales, Aspergillaceae) Belonging to Section Talaromyces in Korea

mycolabadmin

Researchers surveying fungal diversity in Korea discovered one new species of Talaromyces fungus and confirmed five additional species previously unknown to the country. These fungi were isolated from soil, freshwater, and indoor air samples and identified using genetic analysis and visual characteristics. Many species in this fungal genus produce valuable compounds with potential medical and agricultural applications, making them important for biotechnology research.
